This is just a handy little class (with example) that allows a user browse a unix file system when PHP is not in safe mode. This is a script that I have given to some ISPs to check security of their servers when they tell me that their setup is secure.

When files are readable by the web server, they are displayed to you. This script is not limited to $DOCUMENT_ROOT and below. This will browse the entire file system (again, not in safe mode).
